ROTARY MOTOR.

SPECIFICATION forming part of Letters Patent No. 633,669, datedSeptember 26, 1899.

Application filed May 16, 1899. $erial No. 716,927. (No model.)

To all whom it may concern:

Be it known that I, BALTAZAR WILHELMUs TIENHOVEN, a subject of the Queenof the Netherlands, and a resident of The Hague,

Netherlands,have invented a certain new and useful Improvement in RotaryMotors, of which the following is a specification.

The invention relates to rotary steam-motors, and has for its object tosecure the easy and regular working of the same when running at a greatspeed up to fifteen hundred revolutions per minute.

The improved motor requires an exceedingly small expenditure of steam,is of sim- I5 ple construction, and very cheaply built.

The invention is illustrated in the accompanying drawings, in which-Figure 1 is an end elevation of the engine. Fig. 2 is aside elevation ofthe same. Fig. 3

is a plan view. Fig. 4 is a vertical sectional View, and Fig. 5 is adetail view.

The new motor comprises a cylinder furnished with removable covers a andb and with a division plate or disk 6, dividing its interior into twoparts 0 and d, a shaft 1', mounted to rotate in the cylinder, and abucket or vane wheel mounted on the shaft 2'. Steam is admitted througha pipe f into one of the chambers or divisions c of the cylinder,

from whence it passes through slits g and g formed at an angle of aboutforty-five degrees in the division-plate 6 into the other chamber d, inwhich the bucket or vane wheel is mounted, and being directed to im- 3 5pinge against the buckets or vanes causes the wheel to rotate.

The steam-inlet openings g and g are regulated by slide -valves 70,operated through screw-and-lever mechanism Z from a handwheel outsidethe cylinder. The steam passes out through pipe m at the lower part ofthe cylinder.

A fly-wheel and a belt driving-pulley may be attached to the motor-shaftt', or the shaft may be coupled direct with the apparatus to be driven.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

In combination in a rotary steam-motor, the casing, the shaft, apartition arranged within the same, dividing the interior into a smalland a large compartment, a stem-inlet BALTAZAR WILHELMUS 'llENllOlEN.
